Title: Production of waste wraps and thread reserve windings on a bobbin tube
IPC: B65H54/34
Filed: 1975-04-17
Abstract: 1498507 Winding waste and reserve windings MASCHINENFABRIK RIETER AG 17 April 1975 [29 April 1974] 15851/75 Heading D1J This invention relates to means for winding waste windings and thereafter reserve windings. The apparatus comprises a first pivoted lever 5 that is movable by the yarn and exerts a first delay; and a second pivoted lever 6, offset from the first lever, that is movable by the yarn and exerts a second delay. As shown in Fig 1 the levers 5 and 6 are pivoted at 3 and 4 respectively. When the yarn is snagged in a slot 27 in the take-up bobbin 28 the resulting tension in the yarn causes it to tend to move to the left where it will eventually be picked up by a traversing thread guide 32. The yarn first engages lever 5 and as it swings to the left a waste winding C is laid down. The yarn then leaves lever 5 and engages lever 6 whose delay is shorter than that of lever 5 so that a reserve winding D is laid down, the turns of which are spaced apart. On leaving the lever 6 the yarn travels along a straight edge 33 that extends into the traverse range of the thread guide 32. This causes a winding E of widely spaced turns to be laid down and ensures that the yarn is picked up by the thread guide 32. The levers 5, 6 may be biassed against the thrust of the thread by spring means or by gravity or by a combination of these. Lever 5 may have pivot means comprising a cylinder rotatably supported in a bore, the bore being filled with a liquid of determined viscosity.  Lever 6 may carry a slidable weight. Lever 5 may carry a stop maintaining a determined distance with respect to the second lever.

Filed: 1939-05-30
Abstract: 529,982. Two-way repeaters. STANDARD TELEPHONES & CABLES, Ltd., and PROBERT, G. O. May 30, 1939, No. 15918. [Class 40 (iv)] Each of two transmission paths, e.g. of a repeater, includes two attenuation networks AN 1 , AN  2  and AN  3 , AN  4  in series, one normally having high and the other low attenuation. The arrival of speech lowers the attenuation of the high-alternation network in its own path and raises that of the low attenuation network in the other path with the help of control circuits ES 1 , ES 2  shown in detail in Fig. 3. These comprise an input network 1, 2, 9, 10, 15, 16 which presents a high impedance to the line and a constant impedance to the partly tuned input transformer T 1  of a valve V, and can be tapped at different points to give different sensitivities. The input transformer has an additional winding connected to a rectifier bridge X 1  which is biassed by a second bridge X  2  fed by an additional output circuit of valve V 1   so that after a pre-determined level the output level is independent of the signal strength. The signal output of V 1  is rectified by a voltage doubler and applied to a valve V 2  across a small condenser C 8  shunted by a resistance R 4  and a condenser C 7  which is adjustable to give a suitable hangover. Valve V 2  in accordance with the input applied to it causes the voltage between points m, n to be in one direction or the other as in the arrangement described in Specification 503,418. The terminating arrangement comprises two transformers T 5 , T 6  as shown in Fig. 5. The invention may be applied to 3-party conference circuits and sub-station circuits with loudspeakers.

Abstract: 888,826. Drying tobacco. AMERICAN MACHINE & FOUNDRY CO. May 5, 1960 [May 21, 1959], No. 15941/60. Class 34(2) method of drying tobacco comprises the steps of applying a thin layer of material containing tobacco and a volatile component on the surface of a moving conveyer, passing the conveyer over a source of steam, condensing the steam on the underside of the conveyer, and simultaneously sweeping a current of gas over the thin layer of material and drying the material by the combination of heat applied from beneath and the flushing action of the current of gas from above. In apparatus for drying a thin layer of material on the surface of an endless band conveyer C, Fig. 1, the undersurface of the conveyer is heated by the condensation of steam issuing from tubes 22. The conveyer is mounted within a steam box 12 suspended by chains 14 from a frame formed of members 16, 18, which box is surrounded by a downdraught suction housing H comprising upper and lower housings 38, 40, secured to the members 18. The upper housing 38 has a slot 42 for dry air which is drawn cross-wise over the material to remove moisture which is drawn into the lower housing 40 by suction from a fan F provided therein. The housing 40 has a lower transverse duct 46 connected to a suction tube 48 and the fan and the housing 40 also has condensate collection pipes 50, Fig. 2, connected to flexible hoses 52 within the tube 48. The box 12 has aligning rollers 30 to engage the side edges of the conveyer so that the conveyer remains in constant aligned contact with the box despite lateral swaying and has anchor chains 36 secured thereto which are secured to the conveyer to prevent forward motion of the box with the conveyer. In a modification, the box 60, Fig. 8, is mounted on transverse bars 62 having wheels 68 to engage a transverse track 70 so that the box may be moved laterally with respect to the direction of movement of the conveyer in response to a piston 80 which is actuated by a mechanism 82, 86, 88, 90 which indicates the position at the edge of the conveyer C and moves the box accordingly.
